Answer:
900 m
Explanation:
Given that,
A hiker travels 300 m [N], turns around and hikes 550 m[S], and then finds out he has to hike back another 50.0 m [N].
We need to find the total distance travelled by the hiker.
Let north be positive and south be negative direction.
Distance = total path covered
D = 300 + 550 + 50
D = 900 m
So, the required distance is equal to 900 m.
